first embodiment
[0066]FIG. 1 shows a configuration of a signal system according to a first embodiment. The signal system includes a first signal generation unit 1, a second signal generation unit 2, and a cable (connection tool) 30. It should be noted that the first signal generation unit 1 and the second signal generation unit 2 are connected to an error factor measurement device 40.
[0067]The first signal generation unit 1 includes a first signal source 10 which generates a first signal, and a first output terminal 19 which outputs the first signal. The first signal source 10 includes a first oscillator 12, a switch 13, bridges 14a and 14b, mixers 16a and 16b, a local signal source 17, and A / D converters 18a and 18b.
[0068]The first oscillator 12 generates the first signal (such as a high frequency signal).
[0069]The switch 13 is a switch used to connect the bridge 14a to the first oscillator 12 or a terminating resistor.
[0070]The bridge 14a, upon being connected to the first oscillator 12 by the s...
second embodiment
[0138]A second embodiment is an example of measurement method for a case where multiple second signal generation units 2 according to the first embodiment are present.
[0139]FIG. 5 describes an example of a measurement method for a case where four of the second signal generation units 2 are present.
[0140]With reference to FIG. 5(a), a second output terminal 29a of a second signal generation unit 2a is connected to the first output terminal 19 of the first signal generation unit 10 via a switch (connection tool) 32 (referred to as “connection step”). The error factors of the second signal generation unit 2a are then measured by the error factor measurement device 40 (not shown in FIG. 5) (referred to as “measurement step”). The measurement method is the same as that of the first embodiment, and a description thereof, therefore, is omitted.
[0141]With reference to FIG. 5(b), the connection step and the measurement step are carried out for another second signal generation unit 2b. With r...
third embodiment
[0143]A third embodiment is another example of measurement method for a case where multiple second signal generation units 20 according to the first embodiment are present.
[0144]FIG. 6 describes another example of the measurement method for the case where four of the second signal generation units 20 are present.
[0145]With reference to FIG. 6(a), a second output terminal 29a of a second signal generation unit 2a is connected to the first output terminal 19 of the first signal generation unit 10 via a cable (connection tool) 30 (referred to as “first connection step”). The error factors of the second signal generation unit 2a are then measured by the error factor measurement device 40 (not shown in FIG. 6) (referred to as “first measurement step”).
[0146]With reference to FIG. 6(b), the second signal generation unit 2a, for which the error factors have been measured, is considered as a first signal generation unit, and is connected to another second signal generation unit 2b via the c...
